RunnableLambda converts a python callable into a Runnable.
Wrapping a callable in a RunnableLambda makes the callable usable
within either a sync or async context.
RunnableLambda can be composed as any other Runnable and provides
seamless integration with LangChain tracing.
RunnableLambda is best suited for code that does not need to support
streaming. If you need to support streaming (i.e., be able to operate
on chunks of inputs and yield chunks of outputs), use RunnableGenerator
instead.
Note that if a RunnableLambda returns an instance of Runnable, that
instance is invoked (or streamed) during execution.
Default: None |
Either sync or async callable
The name of the Runnable.
An async callable that takes an input and returns an output.
